The oxygen flow meter is attached to an oxygen blender and gas analyser, which makes sure that precise oxygen delivery is being given to the patient. So far, more than 3 million cases of COVID-19 infection have been reported in India. Humidified High-Flow (HHF) oxygen/air is a form of respiratory support in preterm infants where their breathing is spontaneous. BTS emergency oxygen guidelines (2008) state that humidification is not required for the delivery of low flow oxygen (4L/minute and under) or short term use of high flow oxygen for short periods. [6] Some patients requiring respiratory support for bronchospasm benefit using air delivered by HFT without additional oxygen. This study included 316 patients with mild hypoxemia after extubation from May 2016 to May 2018 from two intensive care units in China. Humidified high flow nasal prong (cannula) therapy is a form of non-invasive respiratory support which has been compared to continuous positive airway pressure (CPAP). Delivery of cold dry gas is irritating to the respiratory mucosa, can cause drying and bleeding of the nasal mucosa and can increase metabolic demand by cooling the body.[15]. Humidified High-Flow (HHF) oxygen/air is a form of respiratory support in preterm infants where their breathing is spontaneous. 2 This technology is now starting to be trialed in both palliative care inpatient and community settings. 5. This helps in maintaining the body’s temperature, decreases the inflammation in the airway and maintains mucociliary clearance, which is the cleaning mechanism of the respiratory tract. Nasal cannulae are disposable, reducing the chance of getting infected, which is quite high in patients using an oxygen mask. The maximum gas flow rates can be from 40 to 60 litre per minute, whereas the heating and the humidifying system delivers gases at temperatures between 33°C and 43°C and humidity from 95% to 100%. Experts say the relatively small number of people in the low dose group makes it difficult to know if the effectiveness seen in the group is real or a statistical quirk. The humidifier should always be placed at a level below the patient's head. Medical gas is heated and humidified and delivered at up to 60 L/min. Humidifier with integrated flow generator .
